Definitions

  • the present invention relates to methods and arrangements in a telecommunication system, in particular to methods and arrangements for the reliability handling of idle gap commands received in a unit of a mobile telecommunication system.
  • Universal Terrestrial Radio Access Network is a conceptual term that identifies that part of the network which consists of Radio Network Controllers (RNCs) and Node Bs. This communication network is commonly referred to as 3G.
  • Evolved UTRAN is an evolution of the 3G radio access network towards a high-data rate, low-latency and packet-optimised radio access network.
  • E-UTRA Evolved UTRA
  • E-UTRAN Evolved UTRAN
  • E-UTRAN Terrestrial Radio Access Network
  • UE user equipments
  • the UE should be able to perform downlink measurements on other frequency or other access technologies without significant performance degradation. These types of measurements (i.e. outside serving frequency layer or outside intra frequency) are performed during idle gaps.
  • An idle gap implies a time period that the UE for instance can use for performing such measurements.
  • the UE does not receive or transmit any data or signaling information.
  • Idle gap patterns can be scheduled in the following ways:
  • the network configures all the associated parameters at the time of measurement configuration.
  • the gaps occur periodically.
  • the periodic pattern is used throughout the measurement until modified by higher layer signaling.
  • the UE will not be scheduled during the gaps instead it will perform the requested measurements .
  • the gap pattern is initially assigned to the UE at the start of each measurement via RRC signaling in a Measurement Control message. But during the course of the measurement the gaps can be altered by sending short commands .
  • the network can send information to the UE to indicate whether the UE shall consider the gap pattern to be on or off. When the gap pattern is off the UE may be scheduled during the gap pattern and so will not use the gap to perform measurements. On the other hand when the gap pattern is on, the UE will not be scheduled and so can perform measurements during the gaps.
  • TDD Time Division Duplex
  • GERAN GSM Edge Radio Access Network
  • the UE tunes its receiver to another E- UTRA carrier frequency or to a carrier frequency of another access technology (e.g. UTRA or GERAN) for performing the neighbour cell measurements and/or cell identification.
  • another access technology e.g. UTRA or GERAN
  • neighbour cell measurements as well as cell identification.
  • the UE should first identify the cell. The neighbour cell measurements are performed on identified neighbour cells. While performing such measurements the UE does not receive or transmit any data or signaling information on the serving E-UTRA carrier frequency.
  • semi-dynamic idle gaps will be used in E-UTRAN.
  • a semi-dynamic idle gap pattern assignment one or more gap patterns are initially assigned (or pre-configured) to the UE at the time of measurement configuration via higher layer signalling such as radio resource control (RRC) .
  • RRC radio resource control
  • the gaps can be activated or deactivated by sending short and fast commands, typically "on"/"off"- signals, that are sent on a shared control channel (e.g. L1/L2 control) as proposed in the document 3GPP TR 25.814 "Physical layer aspect for Evolved Universal Terrestrial Radio Access (UTRA)".
  • the commands are sent just prior to the start of gaps.
  • on/off commands can still be used for activating or deactivating an entire gap pattern, i.e. to start or stop the idle gap pattern. Irrespective of the gap pattern type, the on/off commands can also be used at the very beginning, or activation, of the pattern and for terminating the pattern when measurements are over. It should be noted that the conventional way of activating or deactivating the entire pattern is via Radio Resource Control (RRC) signalling, whereby the drawback is that it is slow and therefore may cause performance degradation.
  • RRC Radio Resource Control
  • the main advantage of the "on" /"off" -commands is to provide flexibility to the scheduler since it can schedule users during the gaps if resources are available, if the quality of service is to be met, and if there is sufficient traffic in the buffer.
  • Another main advantage is that HARQ (Hybrid Automatic Repeat Request) initial transmission and especially retransmissions would not be delayed due to measurements during the gap.
  • each pre-configured idle gap pattern is characterized by a start sub frame number (SSSFN) , an end sub frame number (ESSFN) , and an inter-gap length (IGL) .
  • the typical gap length can vary between 2 ms and 10 ms duration.
  • the gap pattern can be configured for a limited duration but also for infinite amount of time, i.e. until the end of the session.
  • the UE can perform downlink measurements unless forbidden by the network via shared control channel (L1/L2 control) as explained above. In case a measurement is not allowed, e.g. by a gap "off"-command, the UE expects to be scheduled for data transmission.
  • the table illustrates an example of the connotation of gap commands and how gap commands can be interpreted. This, however, is purely a matter of definition; alternative approaches could define, for instance, the values 0 and 1 to be specified as gap "off” and gap "on", respectively.
  • the reliability check can be based either on some signal strength or quality thresholds. It can also be based on some bit error rate (BER) target value. This means a received command is regarded as unreliable in case the received signal quality or strength falls between the thresholds or if the BER is higher than the target.
  • BER bit error rate
  • Reliability of the received commands can be improved by using redundant bits (e.g. sending 000 and 111 for 0 and 1 respectively) . But this is not sufficient as this is almost always done (e.g., 2 or more bits per TPC command) but still UE behaviour needs to be specified since redundant bits may also become unreliable.
  • the gap commands sent via shared control channel signalling may be unreliable due to poor radio conditions, insufficient transmit power setting, or, if the user is in the cell border region, inter-cell interference. If, in such situations, an unreliable gap "off" -command is interpreted incorrectly, there will arise two problems: first, the UE will miss the scheduling commands on the shared control channel and the corresponding data sent on DL-SCH on the serving E-UTRA carrier frequency. This will obviously delay the HARQ transmissions and retransmissions. Second, downlink resources, which contain scheduling command and the data on the DL-SCH, will be wasted.
  • a method in a user equipment located in a cell of a mobile telecommunication network comprises the step of receiving signalling gap commands used to activate or deactivate idle gaps for downlink measurements in the neighbour cells.
  • the signalling gap commands may be MAC level gap on/off commands indicating whether or not the user equipment can use the gap for measurements.
  • a second aspect of the invention provides a method in a radio base station in a cell of a mobile telecommunication network.
  • the method comprises the steps of configuring idle gaps in a user equipment in the cell for downlink measurements, and sending gap commands indicating whether the user equipment should receive data or perform downlink measurement during the corresponding gap.

  • the means for performing downlink measurements in accordance with a predefined rule could be partly be implemented by for instance software that is run on one or more processors in the user equipment. Alternatively it could possibly be implemented by hardware, such as one or more ASICs.
  • a fourth aspect of the invention provides a radio base station in a cell of a mobile telecommunication network.
  • the radio base station comprises means for configuring idle gaps in a user equipment in the cell for downlink measurements .

  • the predetermined rule and predetermined behaviour imply that the UE assumes that the next gap is "on", whereby it performs measurement during the entire gap.
  • the UE may also report events or results pertaining to unreliable events (or unreliable gap commands) to the network, which in turn takes some corrective measures such as increase transmit power, congestion control, etc.
  • the UE behaviour is specified in case of receiving unreliable gap commands, whereby unstable behaviour in the network is decreased.
